Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998604, here are decompositions:

43 + 998561 = 998604
53 + 998551 = 998604
67 + 998537 = 998604
107 + 998497 = 998604
181 + 998423 = 998604
193 + 998411 = 998604
223 + 998381 = 998604
227 + 998377 = 998604

Showing the first eight; more decompositions exist.
